چکیده

Recently, it has been shown that a significant number of evolutionarily conserved human-Fugu noncoding elements function as tissue-specific transcriptional enhancers in vivo, suggesting that distant comparisons are capable of identifying a particular class of regulatory elements. We therefore hypothesized that by juxtaposing human/Fugu and human/mouse conservation patterns we can define conservation criteria for discovering transcriptional regulatory elements specific to mammals. Genome-scale comparisons of noncoding human/Fugu evolutionary conserved elements (ECRs) and their humans/mouse counterparts revealed a particular signature common to human/mouse ECRs (>or=350 bp long, >or=77% identity) that are also conserved in fishes. This newly defined threshold identifies 90% of all human/Fugu noncoding ECRs without the assistance of human-Fugu genome alignments and provides a very efficient filter for identifying functional human/mouse ECRs.

Integration of the Genetic Map and Genome Assembly of Fugu Facilitates Insights into Distinct Features of Genome Evolution in Teleosts and Mammals

The compact genome of fugu (Takifugu rubripes) has been used widely as a reference genome for understanding the evolution of vertebrate genomes. However, the fragmented nature of the fugu genome assembly has restricted its use for comparisons of genome architecture in vertebrates. To extend the contiguity of the assembly to the chromosomal level, we have generated a comprehensive genetic map of...

Complete sequencing of the Fugu WAGR region from WT1 to PAX6: dramatic compaction and conservation of synteny with human chromosome 11p13.

The pufferfish Fugu rubripes has a genome approximately 7.5 times smaller than that of mammals but with a similar number of genes. Although conserved synteny has been demonstrated between pufferfish and mammals across some regions of the genome, there is some controversy as to what extent Fugu will be a useful model for the human genome, e.g., [Gilley, J., Armes, N. & Fried, M. (1997) Nature (L...

A genetic linkage map for the tiger pufferfish, Takifugu rubripes.

The compact genome of the tiger pufferfish, Takifugu rubripes (fugu), has been sequenced to the "draft" level and annotated to identify all the genes. However, the assembly of the draft genome sequence is highly fragmented due to the lack of a genetic or a physical map. To determine the long-range linkage relationship of the sequences, we have constructed the first genetic linkage map for fugu....

G protein alpha subunit multigene family in the Japanese puffer fish Fugu rubripes: PCR from a compact vertebrate genome.

We compare the complexity and organization of the G protein alpha subunit multigene family in the vertebrate genomes of mammals and the Japanese puffer fish Fugu rubripes. Fourteen Fugu G alpha genes were identified of the 16 genes characterized previously in mammals, including Fugu genes from the four classes of alpha subunits Gs, Gi, Gq, and G12. Fugu and mammalian G alpha coding sequences ar...

Fugu genome analysis provides evidence for a whole-genome duplication early during the evolution of ray-finned fishes.

With about 24,000 extant species, teleosts are the largest group of vertebrates. They constitute more than 99% of the ray-finned fishes (Actinopterygii) that diverged from the lobe-finned fish lineage (Sarcopterygii) about 450 MYA. Although the role of genome duplication in the evolution of vertebrates is now established, its role in structuring the teleost genomes has been controversial. At le...
